DISTALITY RANK

open access: yesThe Journal of Symbolic Logic, 2022
AbstractBuilding on Pierre Simon’s notion of distality, we introduce distality rank as a property of first-order theories and give examples for each rankmsuch that$1\leq m \leq \omega $. For NIP theories, we show that distality rank is invariant under base change.

Inference for rank-rank regressions

open access: yes, 2023
The slope coefficient in a rank-rank regression is a popular measure of intergenerational mobility. In this article, we first show that commonly used inference methods for this slope parameter are invalid. Second, when the underlying distribution is not continuous, the OLS estimator and its asymptotic distribution may be highly sensitive to how ties in

Ranking Constraints

open access: yesProceedings of the Twenty-Fifth International Joint Conference on Artificial Intelligence, 2016
We need to reason about rankings of objects in a wide variety of domains including information retrieval, sports tournaments, bibliometrics, and statistics. We propose a global constraint therefore for modeling rankings. One important application for rankings is in reasoning about the correlation or uncorrelation between sequences.

Using benzene carboxylic acids to prepare zirconium-based catalysts for the conversion of biomass-derived furfural

open access: yesInternational Journal of Coal Science & Technology, 2017
Benzene carboxylic acid (BCAs) are common and useful chemical blocks, which can be derived from the abundant low rank coals (LRCs) via oxidative degradation. In this work, we proposed a novel strategy to utilize BCAs as raw materials to prepare catalysts

Adaptive reuse of Libre software systems for supporting on-line collaboration [PDF]

open access: yes, 2005
In this paper, the adaptive reuse of Plone; an open source content management system is described. In one instance, Plone has been used as the backbone of a collaboration and communication support infrastructure within a large research project.

Proportional Rankings [PDF]

open access: yesProceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence, 2017
We extend the principle of proportional representation to rankings: given approval preferences, we aim to generate aggregate rankings so that cohesive groups of voters are represented proportionally in each initial segment of the ranking. Such rankings are desirable in situations where initial segments of different lengths may be relevant, e.g., in ...

Evaluation and selection of CORDEX-SA datasets and bias correction methods for a hydrological impact study in a humid tropical river basin, Kerala

open access: yesJournal of Water and Climate Change, 2021
It is well recognised that the performance of climate model simulations and bias correction methods is region specific, and, therefore, careful validation should always be performed.

A note on the gap between rank and border rank [PDF]

open access: yes, 2017
We study the tensor rank of the tensor corresponding to the algebra of n-variate complex polynomials modulo the dth power of each variable. As a result we find a sequence of tensors with a large gap between rank and border rank, and thus a counterexample
